Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

10.4K
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

Major Somatic Sensory Pathways

3.4K
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Molecular Biology

Background:

  • Sonic hedgehog (Shh) is a key morphogenic factor in cerebellar development.
  • Shh signaling regulates progenitor proliferation and differentiation.
  • Shh plays roles in both embryonic and postnatal cerebellar maturation.

Purpose of the Study:

  • To review the essential functions of Shh during cerebellar ontogenesis.
  • To highlight Shh's role in cerebellar development under physiological and pathological conditions.

Main Methods:

  • Literature review of studies on sonic hedgehog signaling in cerebellar development.
  • Analysis of Shh's impact on progenitor cells, neurogenesis, and glial differentiation.
  • Examination of Shh's involvement in cerebellar foliation and maturation.

Main Results:

  • Shh signaling in the ventricular germinal zone drives embryonic progenitor proliferation.
  • Postnatal Shh from Purkinje cells supports external granular layer and white matter neurogenesis.
  • Shh influences Bergmann glial differentiation and promotes cerebellar foliation.

Conclusions:

  • Sonic hedgehog is indispensable for orchestrating cerebellar development from embryogenesis to maturation.
  • Understanding Shh signaling is critical for both normal cerebellar function and treating related pathologies.
